Athletics at the 1908 Summer Olympics – Men's triple jump

This was the fourth appearance of the event, which is one of 12 athletics events to have been held at every Summer Olympics. No athletes from the 1904 Games returned. The triple jump was still "rarely contested at national meets in this era" and once again there was no favorite in the Olympic event.[3]

Canada, Finland, Norway, and South Africa each made their first appearance in the event. The United States competed for the fourth time, having competed at each of the Games so far.

The competition was described as two rounds at the time, but was more similar to the modern divided final. All athletes received three jumps initially. The top three after that received an additional three jumps to improve their distance, but the initial jumps would still count if no improvement was made. The jump format was codified: "The competitor shall first land upon the same foot with which he shall have taken off. The reverse foot shall be used for the second landing, and both feet shall be used for the third landing."[3][4]

These are the standing world and Olympic records (in metres) prior to the 1908 Summer Olympics.
